Primary Problem: Wind Slab
Bottom Line: Avalanches are unlikely across the forecast area. While conditions are stable overall, isolated instabilities may exist within recently drifted snow and wet snow later this afternoon. These considerations are most relevant in steep and consequential terrain where a small avalanche could be dangerous. Adhere to the fundamentals of avalanche safety–beacon, shovel, probe, one at a time on steep slopes and keep eyes open for signs of isolated instability.

We rode out Lionhead Ridge and around the north end to the head of Targhee Creek. Skies started overcast, but cleared through the day as wind calmed from moderate to light out of the west and southwest.... there were two or three shallow small wind slabs below Lionhead Ridge.

Also, on our way out we saw an avalanche in Airplane Bowl that had been triggered during the day today. This slide also broke on the persistent weak layers, 2-3' deep, 150' wide.

Caught: 0 ; Buried: 0

A rider triggered a huge avalanche in the uppermost reaches of Targhee creek. We discovered it on our way out. The best we could tell looking at their tracks was that they had no idea they triggered it, even though part of their tracks were swept away.
